I think I love him, but does he even like me? HELP! PLEASE!?

So, therethis guy and I've been in love with him since day one, (7 years ago) and I don't know how to tell him that I like him. (He also knows I like him.) But since maybe a week ago he's started to ask me if I like him. I've said no, walked away and have said maybe. And about 2 days ago he sent 2 of his friends to see if I liked him. And today I took a risk and sent one of his friends to find out how he feels about me. He said we should talk, and he never came. He called my name, but his friend teasing him, shoved him into a locker and I walked away, I waited but he came out of school laughing with his friends. He looked over at me, but I was with 3 other people, does this make a diffrerence? So, now I don't know how I will stand him. He's in all of my cles including homeroom. So theres no way of avoiding him, escpecially since I sit next to him in 2 cles. If you have suggestions that could help me for tomorrow I would be ever greatful. I'm painicing and streased out. HELP! thx
